Question type: Mathematical calculation
Solution:
25%^2*25%^2+35%^2*75%^2+2*25%*75%*25%*35%*(-0.5)
=25%^2*25%^2+35%^2*75%^2+2*25%*75%*25%*35%*(-0.5)
=0.25^2*25%^2+35%^2*75%^2+2*25%*75%*25%*35%*-0.5
=0.25^2*0.25^2+35%^2*75%^2+2*25%*75%*25%*35%*-0.5
=0.25^2*0.25^2+0.35^2*75%^2+2*25%*75%*25%*35%*-0.5
=0.25^2*0.25^2+0.35^2*0.75^2+2*25%*75%*25%*35%*-0.5
=0.25^2*0.25^2+0.35^2*0.75^2+2*0.25*75%*25%*35%*-0.5
=0.25^2*0.25^2+0.35^2*0.75^2+2*0.25*0.75*25%*35%*-0.5
=0.25^2*0.25^2+0.35^2*0.75^2+2*0.25*0.75*0.25*35%*-0.5
=0.25^2*0.25^2+0.35^2*0.75^2+2*0.25*0.75*0.25*0.35*-0.5
=0.0625*0.25^2+0.35^2*0.75^2+2*0.25*0.75*0.25*0.35*(-0.5)
=0.0625*0.0625+0.35^2*0.75^2+2*0.25*0.75*0.25*0.35*(-0.5)
=0.0625*0.0625+0.1225*0.75^2+2*0.25*0.75*0.25*0.35*(-0.5)
=0.0625*0.0625+0.1225*0.5625+2*0.25*0.75*0.25*0.35*(-0.5)
=0.003906+0.1225*0.5625+2*0.25*0.75*0.25*0.35*(-0.5)
=0.003906+0.068906+2*0.25*0.75*0.25*0.35*(-0.5)
=0.003906+0.068906+0.5*0.75*0.25*0.35*(-0.5)
=0.003906+0.068906+0.375*0.25*0.35*(-0.5)
=0.003906+0.068906+0.09375*0.35*(-0.5)
=0.003906+0.068906+0.032812*(-0.5)
=0.003906+0.068906+(-0.016406)
=0.072812+(-0.016406)
=0.056406
Answer:25%^2*25%^2+35%^2*75%^2+2*25%*75%*25%*35%*(-0.5)=0.056406
